Large signal simulation of photonic crystal Fano laser

摘要

We numerically investigate small and large signal modulation of a photonic crystal laser with a mirror based on Fano interference between continuum modes of a waveguide and a discrete mode of a nanocvaity. Our simulation shows that the instantaneous optical frequency of the laser signal can be modulated at frequencies exceeding 1 THz which is much higher than its corresponding relaxation oscillation frequency. Large signal simulation of the Fano laser is also investigated based on pseudorandom bit sequence at 0.5 Tbit/s. It shows eye patterns are open at such high modulation frequency, verifying the large bandwidth of the laser.
